I'm searching online for a workbook -- preferably similar to http://www.lepointdufle.net, which is the French equivalent of what I'm looking for. Something with the names of the rules, explanations, and exercises. I am posting this in hopes that someone has a favorite site that they've used or heard of.
Alternatively, if anyone has bought a Russian grammar book in hard copy that they found especially helpful, please post that as well. There are so many bad language books out there, so I'm simply afraid to buy without asking first.
Any suggestions would be appreciated!
